Air Conditioning Repair Services FAQs

Common warning signs include weak airflow from vents, warm air blowing instead of cold, unusual noises like grinding or squealing, water leaks around the unit, and higher-than-normal energy bills. In Houston’s extreme heat, if you notice any of these symptoms, it’s crucial to call 75 Degree AC immediately to prevent further damage and avoid costly repairs.

We offer same-day service for most AC repair requests in Houston and the surrounding areas. Our experienced technicians understand that a broken air conditioner in Houston’s heat isn’t just uncomfortable, it can be dangerous. We prioritize emergency calls and typically arrive within hours of your initial contact. For urgent situations, our 24/7 emergency service ensures you’re never left without cooling.

AC repair costs vary depending on the issue, ranging from simple fixes like thermostat adjustments ($75-$150) to more complex repairs like compressor replacement ($1,200-$2,500). At 75 Degree AC, we provide transparent, upfront pricing with free estimates before any work begins. Our technicians will diagnose the problem and explain your options clearly, so you know exactly what you’re paying for with no hidden fees or surprises.

If your AC system is over 10-15 years old, requires frequent repairs, or the repair cost exceeds 50% of a new system’s value, replacement is usually more cost-effective. Newer systems are significantly more energy-efficient, which can lower your utility bills by 20-40%. Our Houston HVAC experts at 75 Degree AC will assess your system honestly and help you make the best decision for your budget and long-term comfort needs.

Yes, absolutely! A clogged air filter is one of the most common causes of AC failure in Houston homes. When airflow is restricted, your system has to work harder, which can cause the evaporator coils to freeze and the system to shut down. We recommend changing filters every 1-3 months, especially during Houston’s long cooling season. Regular filter changes can prevent costly repairs and extend your AC’s lifespan significantly.

AC Installation & System Replacement FAQs

Most residential AC installations take between 4-8 hours for a complete system replacement. For new construction or complex installations, it may take 1-2 days. At 75 Degree AC, our licensed technicians work efficiently to minimize disruption to your home. We’ll remove your old equipment, install the new system, test all components thoroughly, and ensure everything is working perfectly before we leave your property.

Proper AC sizing depends on multiple factors including your home’s square footage, insulation quality, ceiling height, number of windows, and Houston’s specific climate conditions. An oversized unit cycles on and off too frequently, while an undersized unit runs constantly without cooling effectively. Our technicians perform detailed load calculations to determine the perfect size, ensuring optimal efficiency, comfort, and longevity for your investment.

We install all major AC brands including Carrier, Trane, Lennox, Goodman, Rheem, American Standard, and Daikin. Each brand offers different features and price points to match your needs and budget.

Modern energy-efficient AC systems can reduce your cooling costs by 20-50% compared to older units. In Houston, where air conditioning accounts for 50-70% of summer energy bills, upgrading to a high-efficiency system (16+ SEER rating) can save you $500-$1,500 annually. The savings often offset the installation cost within 5-10 years, and you’ll enjoy improved comfort, quieter operation, and better indoor air quality throughout the system’s 15-20 year lifespan.

HVAC Maintenance & Tune-Ups FAQs

We recommend scheduling professional HVAC maintenance twice yearly, once in spring before the cooling season and once in fall before heating season. In Houston’s extreme climate, regular maintenance is essential to prevent unexpected breakdowns during the hottest and coldest months. 75 Degree AC offers convenient maintenance plans that include priority scheduling, discounts on repairs, and comprehensive system inspections to keep your equipment running efficiently year-round.

Our comprehensive tune-up includes cleaning or replacing air filters, inspecting and cleaning coils, checking refrigerant levels, testing thermostat calibration, lubricating moving parts, tightening electrical connections, inspecting ductwork for leaks, measuring airflow, and testing system performance.

In Houston’s demanding climate, preventive maintenance is especially important, it reduces the risk of breakdowns during extreme heat by up to 95%, saves money on emergency repairs, and keeps your system running efficiently when you need it most.

Maintenance is preventive care performed on a working system to keep it running efficiently and catch problems early. A repair call addresses specific issues when your system isn’t working properly. Think of maintenance like regular oil changes for your car, it prevents problems. Repairs are like fixing a breakdown. Maintenance visits cost less ($89-$150) than repairs ($150-$2,500+) and help you avoid expensive emergency service calls at inconvenient times.

Absolutely! Just because your system is running doesn’t mean it’s running efficiently or safely. Hidden problems like refrigerant leaks, dirty coils, electrical issues, or worn components can reduce efficiency by 25% without obvious symptoms.

Air Duct Cleaning Services FAQs

According to the National Air Duct Cleaners Association (NADCA), residential air ducts should be professionally cleaned every 3-5 years under normal conditions. However, Houston homes may need more frequent cleaning if you have pets, family members with allergies or asthma, recent renovations, visible mold growth, or excessive dust accumulation. Regular duct cleaning improves indoor air quality, increases HVAC efficiency, and creates a healthier living environment for your family.

Watch for these indicators: visible dust and debris around vents, musty or moldy odors when the HVAC runs, increased dust on furniture despite regular cleaning, uneven heating or cooling between rooms, higher energy bills without explanation, and allergy symptoms that worsen indoors. If you notice any of these signs, 75 Degree AC can inspect your ductwork and determine if professional cleaning is necessary to restore your system’s efficiency and your home’s air quality.

Yes! The EPA states that indoor air can be up to 70 times more polluted than outdoor air. Your ductwork can harbor dust mites, pet dander, pollen, mold spores, bacteria, and other contaminants that circulate throughout your home every time your HVAC runs. Professional air duct cleaning removes these pollutants, significantly improving indoor air quality. This is especially beneficial for Houston residents with allergies, asthma, or respiratory conditions, helping reduce symptoms and create a healthier home environment.

For a typical Houston home, professional air duct cleaning takes 2-4 hours depending on your system’s size and complexity. 75 Degree AC uses powerful truck-mounted equipment and follows NADCA standards for thorough cleaning. Our technicians clean supply and return ducts, registers, grilles, diffusers, and the air handler unit. We work efficiently while ensuring comprehensive cleaning, and we’ll protect your home with drop cloths and leave everything clean when we’re finished.

Absolutely! Professional duct cleaning provides multiple benefits that justify the investment. Your HVAC system operates more efficiently (reducing energy costs by 15-25%), your home stays cleaner with less dust, your equipment lasts longer, and most importantly, your family breathes healthier air. Research shows that a buildup of just 0.042 inches of dirt can decrease HVAC efficiency by 21%. For Houston families, especially those with allergies or respiratory issues, cleaner ducts mean better health and comfort.

Indoor Air Quality Solutions FAQs

Indoor air quality directly affects your health, comfort, and wellbeing. Most people spend 90% of their time indoors, and poor air quality can trigger allergies, asthma, headaches, fatigue, and respiratory problems. Houston’s humidity also creates ideal conditions for mold, bacteria, and dust mites. 75 Degree AC offers comprehensive indoor air quality solutions including air purifiers, UV lights, HEPA filtration, humidity control, and ventilation improvements to create a healthier home environment.

We offer several effective solutions: air purifiers that remove up to 99.97% of airborne particles, UV light systems that eliminate mold and bacteria, HEPA filters for superior filtration, whole-home humidifiers and dehumidifiers for optimal humidity control (30-50%), and advanced ventilation systems for fresh air circulation. Our experts assess your specific concerns, allergies, odors, humidity issues, and recommend the most effective solutions for your home and budget.

UV (ultraviolet) lights installed in your HVAC system kill mold, bacteria, viruses, and other microorganisms that grow on cooling coils and in ductwork. These biological contaminants can cause health problems and unpleasant odors. UV lights work continuously, providing 24/7 protection by destroying these organisms at the cellular level as air passes through your system. They’re especially effective in humid climates like Houston where biological growth thrives, and they require minimal maintenance, just annual bulb replacement.

Yes, significantly! Medical professionals often recommend improved indoor air quality as part of allergy and asthma management. High-quality air filtration removes allergens like pollen, pet dander, and dust mites that trigger symptoms. Proper humidity control prevents mold growth, and UV lights eliminate airborne pathogens. Many Houston homeowners report dramatic improvement in allergy and asthma symptoms after installing whole-home air quality solutions from 75 Degree AC, leading to better sleep, reduced medication needs, and improved quality of life.

Costs vary depending on the solution: upgraded air filters ($50-$200), portable air purifiers ($200-$800), whole-home air purifiers ($1,000-$2,500), UV light systems ($400-$1,200), and humidifier/dehumidifier systems ($500-$2,000). While there’s an initial investment, the benefits—improved health, reduced allergy medications, better HVAC efficiency, and enhanced comfort—provide long-term value. 75 Degree AC offers free consultations to assess your needs and provide customized recommendations that fit your budget.

Emergency HVAC Repairs FAQs

HVAC emergencies include complete system failure during extreme heat or cold, no heating in winter when temperatures drop below freezing, refrigerant leaks, electrical issues or burning smells, strange noises indicating mechanical failure, water leaks that could cause property damage, and carbon monoxide detector alarms. In Houston’s climate, a broken AC during summer heat waves can be dangerous, especially for children, elderly residents, or those with health conditions. Call 75 Degree AC immediately at (713) 598-2737 for 24/7 emergency service.

Emergency HVAC repairs may include after-hours service fees, but 75 Degree AC believes in transparent, fair pricing even during emergencies. We provide upfront estimates before beginning work, even for emergency calls. While emergency service may cost slightly more than regular business hours, we never take advantage of your urgent situation. Our goal is to restore your comfort quickly and affordably. Many customers find that emergency service actually saves money by preventing further damage from delayed repairs.

For AC emergencies during summer heat: stay hydrated, close blinds and curtains to block heat, use fans for air circulation, and move to the coolest room in your house. If you have vulnerable family members (elderly, young children, or those with health conditions), consider temporary relocation to a cooler environment. For heating emergencies in winter: dress in layers, close doors to unused rooms, use safe supplemental heating if available, and never use gas ovens or outdoor equipment for indoor heating. Never attempt DIY repairs on electrical or gas components, wait for our professional technicians.
